official news from : https://bit.ly/2QkyIbY NASA Glenn Research Center’s Director Dr. Jimmy Kenyon and Chief Counsel Callista Puchmeyer participated in a local symposium that addressed the operational and legal challenges of human spaceflight. The one-day conference was held at the Cleveland State University (CSU) College of Law on Feb.13.   Kenyon gave a keynote that providedContinue reading “NASA Glenn Experts Join Law College to Talk Human Spaceflight “

official news from : https://bit.ly/2QkyIbY NASA’s newest astrophysics observatory, SPHEREx, is on its way to study the origins of our universe and the history of galaxies, and to search for the ingredients of life in our galaxy. Short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, SPHEREx lifted offContinue reading “NASA Launches Missions to Study Sun, Universe’s Beginning”

official news from : https://bit.ly/2QkyIbY Written by Deborah Padgett, OPGS Task Lead at NASA’s Jet Propulsion Laboratory Earth planning date: Friday, March 7, 2025 In Curiosity’s last plan, the team decided to drive toward a very interesting nodular rock. The rover team hoped to do a detailed study of its surface texture over the weekend.Continue reading “Sols 4475-4476: Even the Best-Laid Plans”

official news from : https://bit.ly/2QkyIbY NASA’s BioNutrients series of experiments is testing ways to use microorganisms to make nutrients that will be needed for human health during future long-duration deep space exploration missions. Some vital nutrients lack the shelf-life needed to span multi-year human missions, such as a mission to Mars, and may need toContinue reading “NASA Continues BioNutrients Space-Fermented Food Research”

official news from : https://bit.ly/2QkyIbY New spacecraft that will transport crews to the Lunar and Martian surfaces and return them to Earth may have diverse landing modalities which will function in different landing environments. Additionally, the crew may be deconditioned on landing, impacting their ability to independently egress the vehicles, perform post-landing tasks in aContinue reading “Risk to Vehicle Crew Egress Capability and Task Performance as Applied to Earth and Extraterrestrial Landings”

official news from : https://bit.ly/2QkyIbY Exposure to microgravity induces bone atrophy/bone loss which increases circulating calcium, impacting the renal stone risk. Risk mitigation strategies including exercise and hydration are well-defined although the ability to treat a renal stone during exploration missions is not yet available.

official news from : https://bit.ly/2QkyIbY It is important to protect humans from unintended electrical current flow during spaceflight. The thresholds for contact electrical shock are well established, and standards and requirements exist that minimize the probability of contact electrical shock. Current thresholds were chosen (vs. voltage thresholds) because body impedance varies depending on conditions suchContinue reading “Risk to Crew Health Due to Electrical Shock (Electrical Shock Risk)”

official news from : https://bit.ly/2QkyIbY Spaceflight causes measures of maximum aerobic capacity to decline, which can result in impaired mission task performance. Based on ISS data, if crew adhere to existing exercise schedules and have access to adequate exercise countermeasure systems, then on average, they return with minimal losses of aerobic fitness. New exploration countermeasuresContinue reading “Risk of Reduced Physical Performance Capabilities Due to Reduced Aerobic Capacity (Aerobic Risk)”

official news from : https://bit.ly/2QkyIbY Exposure to the microgravity environment causes muscle size, strength, and endurance to decline. Based on ISS data, if crew adhere to the exercise schedule and have access to adequate exercise countermeasure systems then on average, they return with minimal losses of muscle size, strength, and endurance. New exploration countermeasures systemsContinue reading “Risk of Reduced Physical Performance Capabilities Due to Reduced Muscle Size, Strength, and Endurance (Muscle Risk)”

official news from : https://bit.ly/2QkyIbY Human exploration missions will require robust, flexible Extravehicular Activity (EVA) architecture protocols that include the use of a reduced-pressure cabin atmosphere enabling staged denitrogenation. Use of this atmosphere could result in compromised health and performance to the crewmember due to exposure to mild hypobaric hypoxia; of most concern are theContinue reading “Risk of Reduced Crew Health and Performance Due to Hypoxia”
